摘要
研究了一类三自由度含间隙双边塑性碰撞振动的模型的分岔和混沌运动。建立其Poincaré映射,通过数值仿真和解析解结合的方法揭示了系统通过倍化分岔、Hopf分岔和概周期通向混沌的道路,分析了系统在分岔点附近的复杂的动力学行为。
Bifurcation and chaos of a kind of three-degree-of-freedom plastic vibro-impact system with clearance is studied. Its Poincar6 mapping is established, combining numerical simulation and analysis solution, the paths of the system from doubling bifurcation, Hopf bifurcation and quasi-periodic to chaos is revealed, the dynamics behavior near the bifurcation point of the system is analyzed.
